Evidence emerging from states where marijuana is already legal demonstrates that the legalization of marijuana is failing to achieve the promises made by activists to protect public health, reduce discrimination, and achieve social justice. A recent report from the American Automobile Association shows that Washington State has seen a doubling in the number of fatal drugged driving crashes since legalization. In Colorado, a recent report from the state's public safety agency reveals that after the state legalized the drug, marijuana-related arrests for black and Hispanic youth rose by 58 and 29 percent, respectively, while arrest rates for white kids dropped by eight percent. Moreover, few marijuana businesses are minority-owned even while the vast majority of them operate and advertise in low-income communities of color.
